METAL WINDOW.

Application iled December 10, 1926. Serial No. 153,776.

This invention pertains to metal window construction.

One of the objects of this invention is.V to provide an improved windowconstruction whereb the fit of the sash may be adpisted. Anot er objectis to provide an improved construction in which the friction of the sashisreduced. 1

Another Object to provide a construction which will conceal and protectthe sash cord.

Another object is to provide an improved `construction which will beycheap to `manufacture and which may be adjusted to suit thepeculiarities of each installation.

Another object is to provide anV improved construction adapted to renderthe traine stiff so as to withstand lateral pressure of thesash. i l

Further Objects will appear from the following description, taken inconnection with the accompanying drawing, in which `Figure 1 is avertical section showing a window embodying this invention; I

Figure 2 is a section on line.2-2 of Figure 1;

Figure 3 is a perspective detail of the auxiliary jamb; and

Figure 4 is a Aperspective detail of the anchor for the inside stopfastening.

Referring to the drawing, Figure 1 shows a vertical section of thewindow and the frame, which comprises a lintel 1, a sill .-2 andvert-ical jainbs 3,1 only onev of which is shown in thef drawing. Thelintel 1 has a channel form provided with inner and outer flanges 4 and5. i This lintel is formed with an inwardly extending channel or groove6- and adjacent thereto a. downwardly extend-V ing flange or rib 7. Thesill 2 has a channelled form, which may have `any suitable shape, .suchas illustrated in Figure 1.

Each jamb 3 has a rectangular box forni,

as shown in Figure 2, and is provided withV an inwardly-extending flange8. `The outside of the box vis closed by a plate 9, having an inwardlydirected flange 10, which forms the outside stop whichy guides the uppersash. The plate 9 may be crimped to the jamb 3 -on the outside, as shownat 11, and is also secured to the flange 8 by means vof rivets 12 orother suitable astening.- A gutter 13 may be secured to the outer flange5 of the lintel and run down the outside face of the `15 similar to thatdescribed for the jainb, as illustrated in Figures l and 2. The inneredge of the flange 10 forms the Outer stop which guides the upper sash14.

Thesash V1li may also be of metal andv has Vits stiles formed with anoutwardly extending rib 15 adapted to cO-operate with the flange 10 toguide the sash. An inner guide for the rib 15 is provided by a flange 16formed or mounted on an auxiliary jainb indicated generally at 17. Theauxiliary )amb v17 has a generally channelled form' but is provided withan inwardly extending channel 18, running along the middle thereor. Thischannel is slightly wedge-shaped and eiicloses an inverted U-shapedchannel 19, which serves to fill out the inner part of the channel 18and stillen the saine. lFrom the channel 18, sloping webs 20 extendoutwardly to both sides, terminating in right angle flanges 21. Theflanges 21 are adapted to bear against the inner `face of the jaiiib 3and have mounted therein at intervals therealong adjusting bolts 22.vThe bolts extend through sides of the jainb with the head of the boltvagainst one flange'and as- `cessible for adjustment while the nut isagainst the other flange.

, Mounted on the inner face of the channel 18 is a plate 23, whose edgesare each bent or deflected at obtuse anglesvto form the flanges 16. Theflanges 16 may be straight,

but, as shown in Figure 3, they taper so as to startat the middle of thejamb 17 and iiicrease iii width toward 'opposite ends, merging into theplate at the middle.V The deflection of the flanges as well their isshown exaggerated, for in practice both will be slight. i i

The inner sash 24 is provided with a rib outer other is, in inner othersash 14. This` rib 15 engages the flange 16 of the auxiliary jamb andturn, engaged by a flange on an stop 26. The stop 2 6, as well as theparts above mentioned, may be constructed of pressed sheet metal and hasan outer flange 27, which rests against the jainb13, and an inner lange2S which rests upon the edge of the auxiliary `iamb 17 and serves toclampthe saine against the janib 3 while centered therein. The stop 26is secured in place by clamping bolts 29, having threaded engagementvwithclips `30 on the exposed face of the jainb. These clips are slippedthe sash.

under the projecting ends of pairs of holding lugs 31, cut from theinner face of the jamb 3 and bent inwardly, as shown in Figure 4. Thispermits the stop to be adjusted towards the sash, the clips slidingbetween the lugs. The auxiliary jamb has cut out portions to clear theclips, as shown in Figures 3 and 4.

The meeting rails of the sashes may be provided with flanges 32 and 33,as illustrated in Figure 1. The upper rail of the outersash is arrangedto abut the flange 7 on the lintel when the sash is up. The top rail ofthis sash may be provided with an upwardly extending flange 3-l,whichenters the channel or groove (3 so as to provide a weather seal. Thesash weights 35 may be connected by sash cords, running over pulleys 36and connected to suitable fasteners 37 on the ribs 15. vIt will be notedthat the stops 10 and 26, together with the auxiliary jamb 17, form anenclosure within which the sash cords operate.

It will be noted that the sloping webs 2O give the auxiliary jamb anarched form with the bearing flanges 21 spaced laterally from the crownof the arch. This arched form with spaced bearing points gives greatstiff'- ness to withstand lateral pressure from the sash in eitherdirection. The bolt 22 serves to further brace and stillen the arch.'Ihe plate 23 is carried by the arch and provides a. parting stilebetween the upper and lower sash.

In assembling this window, the lit of the sashes may be adjusted lbyadjusting the auxiliary jamb 17. This is done by means of the bolts 22,before the stop 26 is in place. By drawing the flanges 21 together, theplate is sprung towards the sashes, and `by proper adjustment of thesescrews, the flanges may be sprung to cause them to hear evenly againstthe sash edges. The flanges bear at their edges so asto not only reducefriction but also to scrape as little paint as possible from the metaloli' the sashes. It will be noted that these flanges bear against thecorners between the sash edges and the ribs so as to secure location ofthe auxiliary jamb, which is retained by the flange 28 of the stop 26.

lVhere the flanges 1G taper from the middle to the ends ot the jamb, anychannel 38 formed will'be closed; for by drawing together the sidesbythe bolts 22, the middle, where the flanges 16 disappear, will bebrought into engagement with the edges of This provides a seal againstthe passage of a draft through the space 38,

It will be seen that by the present construction not only is the windowrendered weather-tight all around, but the moving parts are all housedso as to be hidden from view and protected against deterioration.Furthermore, the various parts are adjustable in such a way thata properrunning fit may be provided between the sash and its guides and at thesame time a weather-tight joint is n'ovided.

It wil also be noted that the portion 18 ot the auxiliary jamb forms aparting style on which the bearing plate 23 is mounted. This partingstyle is relatively narrow while the auxiliary jamb has a broad bearingon the main jamb, so that a stilll and rigid parting style is providedwhich is not subject to warping or distortion by the forces acting uponit.

It is obvious that various changes may be made in details ofconstruction without departing from the spirit of this invention; it is,therefore, to be understood that this invention is not to be limited tothe specific details shown and described.
